Abstract:
Objective To analyze the abnormal results of individual dose monitoring for radiation workers in Tongzhou District, Beijing, China, and to propose corresponding improvement measures. Methods Questionnaires were used to investigate the radiation workers who had abnormal dose monitoring results. Results In 2015—2019, among the 12 595 individual dose monitoring results for radiation workers in Tongzhou District, 23 were abnormal. The main type of work with abnormal monitoring results was medical diagnostic radiographer (69.60%). A total of 17 (73.90%) radiation workers had an exposure dose ranging from 1.25 mSv to 5 mSv. Conclusion The abnormal dose results were all from non-occupational exposure, mainly due to the dosimeter left in the workplace. The key to solving the problem is to further strengthen the education and training for radiation workers, to improve the institutional radiation protection management, and to supervise and inspect the relevant work strictly.
